What is CRT?

CRT is a process technology that captures CO2 from existing and operating base load (24 x 7) power plants using fossil fuels and substituting the Oxygen in CO2 with renewable Hydrogen thereby converting CO2 into RNG (renewable natural gas). Then RNG becomes the renewable fuel for the above power plant. It is a perfect example of a circular economy with Zero Carbon emissions.

CRT becomes a link between fossil power industry and renewable industry, and it can achieve zero Carbon emission in the shortest possible time frame averting a catastrophic climate change.

Why CRT?

The climate change is a global issue and it requires a global solution and eliminating CO2 emission by few countries will not address the problem and it will require a collective solution. CRT can provide such a solution.

The world is now divided than ever before into two segments. One segment believes Carbon emission is causing global warming and climate change and therefore CO2 should be curtailed or eliminated completely, and all future energy should come only from renewable energy sources such as solar wind etc to avert climate change.
The other segment believes the science of climate change is not well established and dismisses the theory that CO2 causes global warming and climate change. They believe such a change is a natural phenomenon and it has nothing to do with CO2 emissions.  They fear by simply eliminating fossil fuel usage in the absence of a clear substitute the energy industry will be seriously disrupted causing economic collapse and the security of a nation. For example US has become the largest exporter of oil and gas in the world due to their aggressive policy of exploiting oil and gas reserves using techniques such as fracking. However these resources are finite and their CO2 emissions will become a stumbling block in the near future.

It is a useless exercise to engage in argument without a clear path forward. But I am sure they will certainly agree and support a substitute fuel such as renewable natural gas (RNG) that can generate a base load power with zero carbon emission.

CRT will be able to convince both the above segment of people because it will meet the requirements of both the parties.

The bottom line is we need a system that can guarantee to generate an uninterrupted power 24 x7 with zero Carbon emission irrespective of a method we use if it is sustainable and environmentally friendly.

How do crew in space shuttle get rid of their CO2 emission from their cabin is shown below by NASA.

Carbon recycling technology is like the above process except CO2 is generated by combustion of natural gas as a by-product of base load power generation which is being removed and recycled in the form of RNG (renewable natural gas) using renewable

Renewable energy is a low efficient and intermittent source of energy and it may not meet the world’s energy requirement at the current rate. It will require massive energy storage technologies to be deployed in the shortest possible time frame. According to NREL report a 100 Mw PV solar with 240 Mwh storage battery will cost approx. USD 188 mil. To meet a base load power of 2400 Mwh/day the cost of the system will be USD 1.88 billion. The life of storage battery is assumed only at 12 years and will require replacement at least twice in 24 years of its life cycle. The same capacity 100 Mw combined cycle power plant using natural gas will cost only USD 105 mil with a life of at least 25 years. Therefore, renewable energy alone cannot solve the problem of climate change in its current form. It will be prudent to use renewable energy to generate renewable Hydrogen (RH) from water (even seawater) and use it to decarbonize the fossil economy. In fact, this is the solution  world needs right now.

Large(utility) scale battery will require massive amount of exotic material such as Lithium, Nickel, Cobalt etc which are not renewable and will have a large carbon footprint and disposal of depleted batteries will create massive environmental problems in the future. They are simply not sustainable.

Combined cycle power generation using natural gas is a proven technology that has been used for decades and all the infrastructure required are already in place.

What is involved in CRT?

CRT will involve the following three sections:

  1. Renewable energy facility such as PV solar, Concentrated solar or wind, geothermal, OTEC and hydro etc.
  2. Renewable Hydrogen facility to generate and store Hydrogen using the above renewable energy sources.
  3. Combined cycle base load power plant with CO2 capture and storage using either pre or post combustion technologies.
  4. Conversion of captured CO2 into renewable natural gas RNG which can substitute natural gas in the above base load power plant with zero Carbon emission.

There are number of renewable energy industries established all over the world in the past decade and they are currently operational. The lowest power tariff quoted by renewable energy industry in India is as low as $ 0.035/kwh making it an attractive clean energy source. There are issues in exporting it to the grid due to peak hour supply and demand gap. This renewable energy can be used to generate renewable Hydrogen (RH) by electrolysis of water. Hydrogen can be used as a storage medium to generate power during peak hours using fuel cells. It can also be used to fuel Hydrogen (Fuel cell) cars. Hydrogen cars have many advantages over battery cars based on life cycle assessment. Renewable Hydrogen (RH) is going to help accelerating the decarbonization process of the world soon.

Currently bulk of the power is generated using fossil fuel such as coal, oil and gas. The CO2 emissions can be reduced by 25% by simply switching over from coal to gas. Exiting coal fired power plants can be modified to gas fired plants by replacing their existing boilers. By using RNG the power plant can achieve zero carbon emission while generating base load power.

CRT is a simple and straight forward process technology that can avert global warming and climate change without disrupting existing fossil fuel infrastructure and its power generation while achieving ZERO CARBON EMISSION in the shorted possible time frame. It will promote renewable energy industries in a big way and help decarbonize our economy on a global scale. The cost of renewable energy should further come down so that renewable hydrogen (RH) as well as renewable natural gas (RNG) will become cheaper. Removal of fossil subsidies, taxing carbon emission and subsidizing renewable energy can facilitate such a transition and quicken the process of decarbonization and avert the climate change. A detailed financial model will reveal how quickly and effectively CRT can help countries reduce their emissions.

High CO2 emitting countries such as China, US, India, Australia, Japan, EU and others should adopt this technology .This technology is compatible with transportation technologies such as electric vehicles and Hydrogen (Fuel cell) vehicles because it can generate base load power (24 x 7) with Zero Carbon emission which are essential for the success of the above transport applications. WithoutCRT the transport applications will collapse even if they are “the state of art” technologies. CRT will be an ideal technology for energy intensive industries such as Caustic soda, Aluminium, Steel as well as Carbon intensive industries such as cement.




Fossil fuels such as coal, oil and gas have helped transformed our power and transport industries for decades till now. But recent geo-political situations, depleting fossil sources and Carbon pollution, global warming and climate change have raised serious questions about the future of fossil fuels. However, countries who have massively invested in fossil fuel infrastructure and who have been heavily relying on supply of fossil fuels have started realizing an inescapable truth that they are running out of time to find an alternative to fossil fuels. Recently Hydrogen has been suggested as an alternative source of energy and many countries are gearing up to promote Hydrogen on a massive scale. The countries who have been traditionally using fossil fuels are now focussing on generating hydrogen from fossil fuels as an easier option. But the basic problem with this approach is they still depend on fossil fuels which means they still contribute to Carbon emission and climate change. They can conveniently dispute or deny the fact that man-made Carbon emissions cause global warming in order to score political points among the ‘gullible public’. Democracy is all about numbers and as along as these number stack up the political parties will take advantage of the system and try to push their agenda. But all these efforts are only short term and they still cannot escape the truth that man made Carbon emission is transforming our world for the worst and the future looks bleak.

However, there is a silver lining in the dark clouds of global warming and climate change in the form of renewable Hydrogen. It is now possible to generate Hydrogen using renewable energy sources such as Hydro, solar, wind, geothermal and OTEC (ocean thermal energy conversion systems) that can used not only decarbonize our present economy and also has the capacity to transform future energy and to a cleaner and more sustainable environment. It is now possible to achieve a circular economy in energy sector which means the CO2 emission from existing and operating power plants using fossil fuels can be reversed using renewable Hydrogen so that one can continue to generate power but with Zero Carbon emission. This is a huge transformation.

However, the usage of fossil fuels will continue in other industries such as petrochemicals, polymers and additives, and other synthetic materials. But one can take advantage of using renewable Hydrogen even in such industries using Green Chemistry initiatives so that they can become more sustainable.

However Renewable Hydrogen is a currently very expensive though it is generated from abundantly available natural resources such as sun, wind and water because PV solar panels are made from high purity silicon material again made from simple sand. We cannot afford to take natural resources lightly because they are precious commodities. With limited usage of renewable energy at current levels the cost of PV solar panels is still very expensive but likely to come down as we deploy more and more solar panels in the future. We should also be careful how we use renewable Hydrogen. Our first and foremost usage of renewable Hydrogen should be to decarbonize the fossil economy and achieve a circular economy. It means we must convert CO2 emissions into renewable natural gas (RNG) suing renewable Hydrogen so that the Carbon can be recycled indefinitely with Zero Carbon emission while power plants using fossil fuels can continue to generate a base load power. By this way we will be able to address two issue namely meeting the rising energy demand at a cheaper price while eliminating global warming and climate change. All other use of renewable hydrogen such as Hydrogen vehicles for transportation using fuel cell etc will be secondary because they are not our priority. If we can generate a base load power (24 x7) using renewable Hydrogen with zero Carbon emission, then that should be our focus whether we believe it climate science or not. This will also help us conserve fossil fuels that may be rarely used to meet certain critical needs while substantially reducing the carbon emission.

Renewable hydrogen will require massive deployment of renewable energy projects all over the world. One can generate renewable energy and use it directly for domestic or commercial use. But they are intermittent and require large scale energy storage. Moreover, all HT transmission lines are old and designed for transmitting base load power. Such an approach will not help decarbonizing fossil economy currently widely used. That is why renewable Hydrogen will have to play a key role in the future energy mix. Renewable hydrogen can be used as a fuel for transport industries using fuel cell and Japan is leading the way in this field. But such an application has along way to go and it requires massive investment and creation of infrastructure by way of filling stations. Countries like Japan do not have vast land area for solar industries, and they are likely to use cheap nuclear power and sea water to generate large scale hydrogen infrastructure. By this way they can supply power to both hydrogen as well as electric (battery) vehicles. Alternatively, they are looking to import liquified hydrogen (LH2) from countries like Australia who are ready to use cheap brown coal to generate Hydrogen by gasification despite CO2 emissions. Currently Australian government is not very keen about cutting CO2 emissions, but they are keen to encourage LH2 from cheap coal. They have already approved a pilot plant in the state of Victoria and only future can tell whether such a decision is prudent or not. Japanese companies may prefer to invest in Australia to generate and export clean liquid hydrogen leaving behind all emissions including CO2 in Australia. They may generate LH2 from natural gas and export it to Japan, but it may not be acceptable by Japanese companies because it has a potential to poison the Platinum catalyst used in their Fuel cell cars. In fact, Australia has an enormous potential to generate renewable hydrogen and then use it locally as well as to export. This will be more sustainable in the long run.Toyota mirai layoutToyota mirai power supplyToyota miraiCO2 cloud

Carbon footprint of capital per person as a function of GDP per capitaCarbon emission caused by human beings has become a major issue for our environment and future economy due to changing climate. But there are still few countries who are skeptical about the science of climate change and reluctant to act and refuse to be a part of United Nation’s action on climate change. These countries are either fossil fuel producers such as coal, oil and gas or large economies who have been traditionally depending on usage of fossil fuel for their economy and security. The transition from Carbon economy to non-Carbon economy may not be easier for them is the absence of an alternative technology that can guarantee not only complete elimination of CO2 emission but also efficiency and sustainability. There is a strong political motivation too behind such dithering and they create a fear of slowing economy and large-scale unemployment among the people in the absence of a viable alternative energy source. Therefore, United Nation has an important role to play at this critical juncture of transition to non-carbon economy and save the planet earth from imminent danger of environmental and economic collapse. UN can also stop mass extinction of species and migration of refugees for a better life.

UN was successfully able to bring together 174 countries to the negotiating table during Paris climate change conference. However, they failed to reach a unanimous Agreement and announce a concrete action plan to act. They failed to articulate the ways and means of reducing or eliminating man made CO2 emissions in a stipulated time frame. They also failed to bring powerful nations such as USA to the table which made the task even harder. But this situation can be changed if UN is able to articulate a concrete Action plan which is agreeable to all the parties involved. This is possible only if UN can address all the issues involved such as the alternative technology, funding, implementing in a stipulated time frame, measuring and monitoring the progress and achieving the final goal. UN should first be able to create the same level playing field where all Countries can take part equally without any discrimination. It depends completely on focusing the type of technologies to be deployed to achieve the above goals and It should be able set a specific date to implement such a plan. Currently renewable energy is considered as one of the alternatives along with renewable Hydrogen which can act both as an energy storage and as well as energy carrier. But renewable Energy is intermittent and energy storage has become part of the system. With our limited experience in renewable energy deployment over a decade renewable energy alone Cannot be the solution to address the issue of CO2 emissions. One must estimate the life cycle CO2 emissions of hardware used in renewable energy systems such as PV solar panels, Solar concentrators, wind turbines, storage batteries. Renewable Hydrogen generators, Fuel cells etc. Each of them has their own Carbon footprint that must be incorporated in life cycle assessment.

Similarly, even fossil fuel-based power generators such as boilers, steam or gas turbines, pumps and compressors etc too have Carbon footprint that should be assessed. Carbon footprint should be assessed as fixed carbon footprint and variable carbon footprint and then these data should be used to arrive at the Carbon footprint to generate power (tons of CO2/Mwh) Once a life cycle assessment of their Carbon footprint is estimated then it will be easier to rate each technology based on their “Carbon Rating” which will be a measure of their Carbon footprint. The Carbon rating is measured and allocated “number of stars” based on Carbon footprints. Lowest emitting technology will be rated with highest number of stars while highest emitting technologies will get the lowest number of stars.

Carbon rating will be a good measure to assess the technology that can be used worldwide. Countries who are reluctant to reduce CO2 emissions will be discouraged to participate in government and private tenders worldwide and exports. Such countries will be treated as “Pariahs” and rejected by consumers due to their low Carbon rating. Technologically advanced countries or companies who can use fossil fuel but with lowest or Zero CO2 emissions will also be able to compete with renewable energy technologies. Carbon Rating will offer everybody the same level playing field. Carbon is the fundamental building block of organic life on earth which is essential for human survival but unabated CO2 emission by human activities is the culprit. I strongly believe Zero Carbon emission can be achieved even while using fossil fuels by constantly recycling CO2 in the form of regenerated synthetic natural gas. It will not only eliminate CO2 emission but also generate synthetic fuel using renewable Hydrogen without any necessity to exploit fresh fossil fuels. Using renewable Hydrogen as a storage medium or as energy carrier may be expensive due to inherent nature of Hydrogen atom. UN can introduce Carbon Rating as a single tool to measure the Carbon footprint of a specific technology with the lowest or Zero CO2 emission worldwide to start with. They should be more proactive in promoting technologies with highest Carbon rating and encourage countries to adopt such measures.


Energy generation and usage is considered not only as a mark of progress of a nation but also security of a nation. That is why countries go to extraordinary distance to achieve such a security and everything else becomes secondary in the path of their goal. That is why countries with high oil and gas reserves enjoy good relationship and privileges with powerful nations of the world. Countries who do not have their own oil and gas reserves and who completely rely on import of oil and gas have no choice but maintain a good relationship with oil rich countries despite their difference in ideologies and policies. But with warming globe and changing climate the dependence on fossil fuels is fast becoming unsustainable and countries look for alternatives. It is good news for the whole world especially for nations who depend completely on import of oil and gas because they can develop their own renewable energy sources to lower their emissions. But there is one major difference. Countries who depend on import of oil and gas required to develop only an infrastructure to store and distribute oil and gas, But with renewable energy they have to develop an infrastructure to produce the hardware necessary to use alternative energy sources such as solar, wind, geothermal  but also energy storage such as batteries. The warming globe and changing climate have become a grave threat to the plant earth and a threat to lives of entire future generations. It is the greatest challenge of the industrialized world. One can view this as threat or as an opportunity. But it is time to act irrespective of our views and we must act now.

It is an opportunity for scientists and engineers to view energy sources and their applications in a new perspective. It is an opportunity to understand how human activities affect our environment and how not to damage them but preserve them for our future generations while developing new alternatives. Humanity is just a part of a larger environment and any damage to planet earth is at our own peril. It is an ancient wisdom, but we neglected them. When an aboriginal of Australia said “we belong to earth and earth does not belong to us” we failed to listen to them. We(people) became bigger than They (environment).

In pursuit of a new energy source one must be extremely careful in examining Nature and how she operates so that we do not make the same mistakes of the past. As we develop renewable energy as a potential energy source of the future, we should be aware of the life cycle of such a system and their impact on environment. Renewable energy requires hardware that uses exotic metals, catalysts, polymers, new Carbon sources and glasses. As we switch to Carbon free economy, we should make sure that there are no emissions in developing renewable energy sources and if necessary impose Carbon tax on such emissions and, to develop recycling technologies to recycle that hardware safely and environmentally friendly manner. It is critically important issue as we move forward. According to an article published in Chemical engineering News

“The potential quantities of waste are enormous. By 2025, waste batteries removed from electric vehicles will total 95 Giga watt hours, according to an estimate by Bloomberg New Energy Finance. That pile will weigh roughly 600,000 metric tons.

A similar amount of old solar panels will have accumulated by then, according to projections by the International Renewable Energy Agency. IRENA anticipates solar panel waste could reach 78 million metric tons by 2050. And Europe could see 300,000 metric tons per year of decommissioned wind turbine blades in the next two decades, says the trade association Wind Europe.

Each year, approximately 300,000 metric tons of lithium-ion battery waste is generated around the world, says Sheetanshu Upadhyay, an analyst with India’s Esticast Research & Consulting. Most of those batteries come from mobile devices, but that waste will soon be overshadowed by old electric car batteries. Sales of plug-in electric vehicles are expected to surpass 2.6 million in 2020, according to Navigation Research.”

The above data shows the amount of CO2 emission associated with implementation of renewable energy sources soon. There is a potential for large scale recycling industries on renewables, but it will come with a price and environmental issues. Right now, the main problem is the CO2 emission and the only way to tackle this problem is impose Carbon tax on emissions while encouraging industries with low emission technologies. It should be possible for UN to pass a unanimous resolution among the nations to address climate change by imposing Carbon tax uniformly across the nation. By such resolution UN can bring all those countries to the table who are currently reluctant to be a party to the Paris accord. Countries can use “Carbon rating” similar to “energy ratings” currently used for measuring energy efficiencies in appliances such as Heaters and air-conditioners. The lowest emitting technologies will get the highest Carbon rating while high emission technologies will get the lowest Carbon ratings. By using such a method country who are reluctant to act on climate change will be disadvantaged; they will not be able to compete in international market or export their goods to low emitting countries based on Carbon ratings.

Generating electricity using fossil fuel is a well-established technology, that has been practiced over several decades all over the world, despite its low efficiency. But this technology inherited certain disadvantages even before it was commercialized such as post combustion emissions, large amount of waste heat, and water intensity. Millions of people died of Carbon pollution over decades. Large scale usage of water both inland and on shore power stations created shortage of drinking water in many parts of the world resulting in desalination technologies creating its own environmental issues. Large scale mining of coal and unsustainable exploitation of oil and gas both on shore and off shore caused enormous environmental pollution. However, such emissions were completely ignored while the world celebrated the discovery of electro-magnetism, steam engine and petrochemicals. Millions of people were employed, and industries grew worldwide. Energy became synonymous with security of a nation. Population grew exponentially. However, we have reached a point in the history of mankind and all great discoveries once acclaimed as human achievements have started a new painful chapter of warming globe and changing climate for new generations to deal with. It is a great challenge of our time, but new generation can take this challenge and convert them into opportunities. The past lessons can show them a new clean and sustainable pathway while dealing with ever increasing population growth.

The challenge for the new generation is to curtail and eliminate Carbon pollution completely while meeting the energy demand in a time bound manner because we are running out of time. Currently renewable energy generation is too low to meet these challenges within the time frame to avert disastrous consequences scientists predict. Renewable Hydrogen is a potential substitute for fossil fuel to eliminate Carbon pollution but that will not solve our current problem soon because renewable energy generation is too small and too slow while our energy demand is huge. Battery technology is only a storage technology and without a base load power generation all other forms of technologies will not meet our current challenges. I am not discounting the potential of renewable energy and its critical role in the future energy mix but that alone will not solve the current crisis. Hydrogen is a weak and unstable atom and it requires a backbone such as Carbon. That is why Hydrogen do not exist in a free state in Nature, but it exists in the form of water or natural gas. Therefore, it is only logical to convert renewable hydrogen into renewable natural gas so that it can be used as a fuel as we have been using for decades. It does not require to create a special type of infrastructure such as required for Hydrogen or any storage technologies.

Our focus should be to achieve Zero Carbon emission in the shortest time scale possible while generating a base load power of 24 x7 using a renewable energy source. It looks like a daunting task but, it is not too big a challenge to overcome. In fact, the technologies are already available, and we are almost there to achieve the above, but governments should understand the challenge and its gravity and extend all the support it requires. Government around the world should implement the following with great urgency to achieve the above objectives.

1.Tax Carbon with immediate effect and minimum tax should be $500/ Mt of CO2 emitted. It should be centrally monitored by government agencies with appropriate technology implementations.

  1. Encourage Oxy combustion technologies for coal, oil and gas-based power plants with incentives to eliminate emissions pollution and reduce the cost of Carbon capture.
  2. Encourage large scale deployment of super critical Carbon dioxide power generation technologies with liberal grants and low interest loans for research and development of super critical CO2 technologies using Brayton cycle using fossil fuels with Zero Carbon emission.

4.Encourage large scale deployment of SNG plants using CO2 and renewable Hydrogen.

By using the above steps all fossil fuel-based power plants existing and operating can be converted and continue to generate base load power 24 x7 with Zero Carbon Emission within a time frame. Simultaneously it will generate large scale renewable hydrogen and renewable synthetic natural gas which can generate base load power with Zero Carbon emission. Such Zero emission power plants can then power all electric and fuel cell cars and eliminate Carbon pollution completely from our roads. The above implementation will create millions of jobs worldwide!

The greatest advantage of these technologies is to recycle Carbon indefinitely while generating power using renewable natural gas with Zero Carbon emission and fresh fossil fuel usage will be gradually eliminated from our planet earth.


There is a growing concern among the nations in the world about the changing climate due to greenhouse gas emissions (GHG) and the natural disasters associated with them such as loss of human lives and billions of dollars’ worth of damages in assets. Yet there is no political will or consensus among the largest emitters of CO2 on Carbon emissions at the peril of their own economy and the rest of the world. Paris agreement remains on paper, but largest emitters are either moving away from such an agreement or they continue to emit CO2 without any regard to their agreement. Unfortunately, such a situation has risen due to a scepticism among the public and politicians about the relationship between greenhouse gas emissions and climate change. They believe science has failed to establish a clear evidence between GHG emissions and climate change. Secondly there is a fear among the public and politicians that complete elimination of CO2 will be a prohibitively expensive exercise and such expenses will be eventually passed on to the consumer and such a move will make the governments in power unpopular and it is a risk and they may lose their future elections as a government. Some countries such as US, Australia and many EU countries believe elimination of CO2 completely will lead to job losses and lead to closure of industries such as automobiles, coal mines, steel plants, cement plants and make the government unpopular. All these notions are based on an erroneous belief that it is impossible to eliminate man made CO2 emissions from earth without compromising an economic growth or risking high energy bills.

CO2 emissions can be eliminated by simply converting them back into a fuel using renewable Hydrogen. For example, CO2 emissions by using natural gas such as combined cycle or cogeneration/ trigeneration plants can be recovered and converted back into SNG using renewable Hydrogen so that natural gas can be substituted with SNG. Such substitution will spur the growth of renewable energy industries such as solar, wind, geothermal and biogas in a big time while fossil fuel industries can continue their operations with Zero Carbon emissions.

But this will be practically possible only if renewable hydrogen industry is suitably rewarded while penalties are levied against CO2 emitters. The market will take care of the rest of the issues and government can stay away from the politics of Carbon and allow industries to address GHG emission problems. Currently the cost of recovering CO2 from polluting plants is about US$ 75/Mt and therefore Government should tax polluters at least at the rate of US$ 100/Mt and pass it on to renewable Hydrogen generators @ US$ 100 /Mt of CO2 eliminated as an incentive.

It will lead to a healthy and robust industrial growth, large scale employment and guaranteed sustainability. It will completely eliminate the necessity to store energy. At the same time, it can also help create alternative energy technologies such as batteries and Fuel cell etc and eliminate CO2 emissions from transportation.  Renewable Hydrogen can supply energy sustainably and there will be no need for mining coal or exploring oil and gas to manufacture Nitrogenous fertilizers. Petrochemical industries too can continue their operations without CO2 emissions. The only requirement will be to design a plant for a pre or post combustion CO2 recovery and Oxy-combustion technology for fossil fuels.

CRT Carbon Recycling Technology known as “Ramana Cycle” is a new patented concept and system that addresses current problems faced by energy industries with a single solution.

Current problems:

1.Renewable energy is only a fraction of total energy generated world-wide. Fossil fuel especially natural gas in the cleanest and most widely accepted fuel for base load power generation. However, it emits CO2 a greenhouse gas causing climate change.

  1. Electric and Fuel cell cars can eliminate Carbon emission from our roads, but it will dramatically increase the electricity requirement which cannot be met by renewable energy sources alone. Eventually the electricity demand will have to be met by fossil fuels which will sharply increase CO2 emissions in a short span of time thus exacerbating global warming.

3.Grid connected renewable energy has many problems due to intermittent nature of renewable energy such as synchronicity, electronic interface with HT lines, metering etc. There is at least 22% loss while transmitting renewable energy into the grid creating dispatchability issues. Power is transmitted 24 x 7 on HT lines.


CRT addresses all the above issue with a single solution as described below.

CRT synthesizes a synthetic fuel CH4, a Hydrocarbon known as SNG (synthetic natural gas) using Carbon from CO2 emissions of gas based power plants and renewable Hydrogen generated using renewable energy sources such as Hydro/solar/wind /biomass/geothermal etc. Once SNG is generated then it can substitute natural gas currently used in power generation. It means one can generate their own SNG and need not depend on oil and gas industries and use conventional gas turbine and generate base load power and transmit using existing transmission lines. This power can be used by electric as well by Fuel cell cars. There will be a net Zero Carbon emission. Additionally the system can supply Hydrogen to Fuel cell cars as an option.

CRT can be implemented using existing systems supplied by internationally known companies with proven technologies and systems. There are absolutely no commercial risks whatsoever. These systems can be deployed immediately, and they are commercial ready.

Each plant is designed specifically based on the capacity, location and purpose. This technology is the first of its kind in the world and it can end the Carbon emission from power plants as well as from automobile industry for good. CRT flow diagram






CRT flow diagramIt is now possible to convert your CO2 emissions from gas fired power plants into synthetic fuel thanks to cheap solar energy! Once you convert into synthetic fuel then you can recycle it so that your industries can power for good. It is a great way of storing your solar energy into a readily deployable fuel source. By generating heat and power from the synthetic fuel the industries can reap enormous economic benefits while achieving Zero Carbon emission. It is a win situation for people, environment and the governments around the world.

CEWT can demonstrate such a system to potential customers who are currently generating power using natural gas. If you are running a Caustic soda plant where you get Hydrogen as a by-product we can use that Hydrogen and generate additional Hydrogen by installing PV solar panels so that the CO2 emissions from your power plant can be converted back into synthetic fuel. That mean you can generate your own fuel and power at fraction of a cost while achieving Zero Carbon emission. You can even run your fuel cell car from the above Hydrogen. You may be eligible even for Carbon credit for curtailing the Carbon emission from your power plant.

When we started blogging about this technology 7 years back the same idea was not entertained by financial institutions and governments. Thanks to the awareness of climate change and Carbon pollution created by 190 countries who signed the Paris agreement. Though many countries agreed to cut their Carbon emission they could not fulfil their obligations under the treaty for various reasons. The emissions have gone up in 2016.

CEWT can undertake this CRT Carbon recycling technology (patent pending) in countries like India and China where Carbon pollution is rampant and energy demand is increasing at the fastest rate in the world. The cost of solar energy in India has come down substantially thanks to the aggressive promotion of solar industry by Government of India.

CRT is an ideal technology for caustic soda plants to reduce their power consumption and to convert their Carbon emission into a synthetic fuel. It is much easier for them to use their Hydrogen one of the by-products of the industry and they can easily supplement with Hydrogen generated from solar power. By using CRT caustic soda plants can reduce their cost of production by energy efficiency, obtain Carbon credit for Carbon reduction and achieve and price stability for their products.

We can demonstrate the technology by installing a model plant in your country and show case many possibilities. It is the beginning for a Carbon free energy of the future and great potential for Hydrogen cars and to eliminate Carbon pollution that is chocking New Delhi and Beijing.

Renewable Hydrogen usage

The technology towards zero Carbon emissions from transportation has gained importance due to increasing air pollution from automobiles. It is not just the Carbon emission but oxides of Nitrogen and Sulphur, but also water vapour (more potent Greenhouse gas) to gather with particulate matters that compounds the emission problems.

Current automobiles based on Internal combustion is not only energy inefficient but generates noise and air pollution. Therefore, battery cars and Hydrogen cars are increasing in popularity and competing with each other. We can examine the merits and demerits of these two technology for a better understanding.

Transportation uses mechanical energy derived from thermal energy generated by combustion of fossil fuels but battery cars as well as hydrogen cars convert an electrochemical energy into mechanical energy. As we know energy can neither be created not destroyed but can be converted from one form to another form. The word “energy storage” is a misnomer because electrical energy is generated at the point of usage from stored chemicals by way of redox reactions. In both cases, we generate electrical energy from batteries or from Hydrogen through Fuel cell and then convert it into mechanical energy. Both battery as well as Fuel cell convert chemical energy into electrical energy by electrochemical reaction namely redox reactions. For a redox reaction, we need both reduction (reductant) and oxidation (oxidant) reactions to take place simultaneously to effect flow of electrons from corresponding ions which we call electricity. It is clear from the above we need two reactants namely reductant and oxidant. In batteries both the reactant and oxidant are stored in solid form or in a liquid form in ‘flow batteries’. The chemistry of the redox reaction will determine the speed, size and the life of the battery. This creates a constraint on the size, weight and life of the battery to achieve a specific mileage. It means battery has a limitation when comes to size, life and mileage to be achieved. Tesla is currently leading the way in batteries both for stationery as well as transport applications. For stationery applications the space, weight and life may not be a big constraint but the life is a constraint and therefore the cost.

But in transport applications all the above three parameters are critical and therefore battery may not be a long-term solution. In Hydrogen Cars Hydrogen gas is stored in a compressed form at high pressure in a cylinder. There is no Oxygen storage but only air is used as the Oxidant. Fuel cell uses both Hydrogen and Oxygen to generate electrical energy at the point of usage to run the motor. Electricity is not stored. The main difference between battery and fuel cell is, battery carries both Oxidant as well as reductant on board in solid form which weighs and occupies space; Fuel cell carries only Hydrogen as the reductant in gaseous form and not Oxidant. Hydrogen is a light weight and only the storage tank in the form of composite material is the actual weight. Moreover, there is more room to store Hydrogen like a Hydrogen bus which carries cylinders at the roof top. If we use renewable energy source such as solar and wind then Hydrogen generation and dispensing will not be a serious constraint for Hydrogen generation and distribution in the future. The biggest disadvantage with Fuel cell is the cost due to expensive catalyst such as Platinum.

Each technology has its own advantages and disadvantages but the fundamental facts of these technologies will give us a glimpse of the future potential. In battery technology storing the reactants in solid form is an issue. Air metal battery has a good potential yet a long way to go. Similarly, if Hydrogen can be generated at the point of usage without storing Hydrogen on board that will open a greater potential. There may a hybrid solution in the future that can integrates both battery and Hydrogen- Fuel cell technologies will be the way forward. Research is being carried out to design a rechargeable Fuel cell battery with enhanced performance and cyclability. Such technologies will also guarantee a clean renewable energy storage technologies for stationery applications in the future. Hydrogen can be derived from many abundant natural sources such as seawater as I have explained in my previous article “CAPZ desalination technology uses only sun, sea and wind”.Toyota mirai power supplyToyota mirai layout

Many people argue that Hydrogen is not an energy source but an energy carrier. Hydrogen is certainly an energy source by itself but is to be derived from other primary sources such as water or natural gas because Hydrogen is not available in a free form. Generation of Hydrogen from its sources require an additional energy but when such an energy is provided by renewable sources such as sun, wind and sea then the cost becomes secondary in the long run. Therefore, battery may not be able to compete with hydrogen in the long run though it provides a temporary solution to pressing power problems in short term. Moreover, batteries rely on materials like Lithium whose availability is limited even though they are recyclable.

CAPZ (Clean water at affordable price with zero discharge) is a new desalination concept that separates seawater into fresh drinking water and industrial salt both simultaneously using only sun and wind power. Seawater is nothing but fresh water in abundance with valuable mineral salts dissolved in it. These minerals include Sodium, Potassium, Lithium and Magnesium and a host of other minerals in traces. It requires a holistic approach to separate them in their pure form along with fresh water for potable and industrial applications. CAPZ technology precisely attempts to do that so that the seawater intake can be put into huge economic usage while reducing or eliminating completely the discharge of highly saline effluent contaminated with chemicals back into the sea. With increasing demand for fresh water and depleting sources of fresh water due to natural and man-made causes , sea water has become an important source for fresh drinking water. Sea water is not only a source of fresh water but also a new source of clean Hydrogen an energy of the future. It requires only sun ,sea and wind to achieve this!
